The expansion of the partial differential equations models of the ABR system and the condition of the communication process

The ABR characters have been used especially in medical fields. But the ABR detail system is not sufficiently clear. Therefore the studies of the ABR system and the Life Support system have been performed. Especially from such view point as information and communication process the ABR characters are needed to be discussed. In this paper the expanded partial differential equation models of the ABR system are derived and from these characters such a kind of the ABR system model as the information and communication process model is proposed taking account of the concept to be based on the Peirce´s Semiotics. And some examples of the method to analyze the ABR system are shown to discuss the background theory of the ABR system from the view point of the information and communication process and improve the Life Support system from the phase of such a theory.
